ABSTRACT:
A noise suppressor for reducing noise resulting from venting of large volumes of high pressure gas. A first pipe member has an open first end, adapted for attachment to a high pressure gas outlet, and a closed second end. A plurality of second pipe members are attached to the first pipe member sidewall and communicate through openings in that sidewall with the interior of the first pipe member. Within the second pipe members a number of plates are positioned, each having several parallel elongated slots therethrough. The plates within each second pipe member are slanted, with the direction of slant alternating between consecutive plates. Preferably, the consecutive plates are rotated 90.degree. and the elongated slots are slanted with respect to the plate surfaces. A further plate member is provided normal to the second pipe member longitudinal axis. The noise suppressor can be coupled to the high pressure gas outlet by valves or directly. The noise suppressor substantially reduces the noise of the venting higher pressure gas.
